Understanding and taking care of dry skin

FALSE. Dry skin is caused by a lack of lipids in the skin. It is therefore possible to have healthy but naturally dry skin. On the other hand, unsuitable hygiene products can accentuate dryness... But this is not, in this case, a hygiene defect as such.

TRUE. Cold exacerbates dry skin. In winter, the body makes the vessels on the surface of the skin shrink. This is called vasoconstriction. The purpose is to retain heat in the vital organs. At the expense of the epidermis. If you combine this with a "hot-cold" alternation between overheated interiors and exteriors, you have all the elements to dry out the skin.

TRUE. The reason is simple. Because it is not protected by clothing like the rest of the body, the skin of the face is in the front line of external aggressions: heat, cold, pollution. Not to mention that the skin on the face is thinner and more fragile. Remember that the hands are also affected.
